Interesting...
I took another look at your domain.xml and I think I found it. In your
cluster-config, you have:
<network-listener port="24848" protocol="pu-protocol" address="${HTTP_LISTENER_ADDR}" transport="tcp" name="admin-listener" thread-pool="admin-thread-pool"></network-listener>
However I don't see a definition of HTTP_LISTENER_ADDR anywhere in the
file. Specifically, the i26 <server> element doesn't define an
HTTP_LISTENER_ADDR system property.
